fc16 livecd and microcode_ctl...

[Rob Healey]

Dear Adam:

I am very grateful for the information that you sent to me about the bug
tracker report!  It shows me that I am not the only one having this problem!

>From the bug tracker, it listed the close date of 2011-June-29.  How long do
you think it might take to filter down to the package list for rawhide?  If
it is soon, then I will wait and not use the workaround...

If it is going to take a while, then I might update and use the workaround
until it is fixed ...

Sincerely yours,
Rob G. Healey

I don't know. The workaround would be to disable that service, though
I'm not sure if you can manage that from a live CD. Interactive boot is
probably broken these days, I don't know if systemd implements anything
like it.

The bug here probably isn't really that microcode_ctl fails, but that
the failure is fatal to boot - it shouldn't be. Microcode updating
should be entirely optional and if it fails, boot should just continue.
It's entirely possible this is what happens in F15, if you look at it
carefully. Looks like this is filed as
https://bugzilla.redhat.com/show_bug.cgi?id=715118 .

Ah - which also gives a hint to avoid it: blacklist the 'microcode'
module. That should be possible from the bootloader, I think.
